Preliminary paleopalynology of the Kanguk Formation (Upper Cretaceous), Remus Creek, Canadian Arctic Archipelago: I. Marine Palynomorphs
Bibliographic record
Abstract
A 39 m section of the Kanguk Formation (Upper Turonian to Lower Campanian) on Remus Creek, Ellesmere Island, was sampled at about one inetre intervals to provide stratigraphic control on palynomorph taxa present. These samples yield well-preserved marine and terrestrial palynofloras represented by a total of 181 taxa, of which 103 are dinocysts and acritarchs and represent 51 % of the population. Based on the abundance and type of taxa present the section can be divided into a lower, dinocyst dominated interval, and an upper interval, where dinocysts are present in lower numbers and terrestrial palynomorphs dominate. In the lower part dinocysts are abundant, diverse and well-preserved. Chorate cysts are the most abundant in terms of species diversity and numbers of specimens, however, cavate dinocysts are common also. In turn, in the upper part of the section, marine palynomorphs are much less common, poorly preserved and sporadic in occurrence. Acritarchs account for a small but significant proportion of the marine assemblages. Small numbers of taxa of Albian-Cenomanian age are considered to be reworked from the underlying Hassel Formation. This indicates an unconformity between the Hassel and Kanguk formations.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
